Shingle roof wind and other damage

{"time":1691639991037,"blocks":[{"id":"Oi-KqLK18d","type":"paragraph","data":{"text":"Even modest wind speeds during a typical thunderstorm have the potential to inflict harm upon shingle roofs, and as wind velocity intensifies, the effects can become more pronounced, as stated by the National Weather Service. However, the severity of wind-related impact encompasses more than mere wind speed, and there are instances where other sources of damage exhibit resemblances to the effects of wind on shingles. Discerning pivotal attributes of wind damage and alternative perils, along with the contributing elements to each, serves as a crucial framework for an accurate determination of the underlying cause of loss."}},{"id":"9C7MsSIXZh","type":"paragraph","data":{"text":"Defining Wind Damage "}},{"id":"G1ldI2B0fG","type":"paragraph","data":{"text":"It's pertinent to acknowledge that some shingles may encounter wind-induced effects without compromising their functionality. The primary role of shingles is to repel water and safeguard the roof structure from harm; unless their capacity to fulfill this function is impaired, they wouldn't be classified as damaged. Shingles displaying traits such as creasing, dislodgment, or removal could signal wind damage. Wind might prompt unsealed shingles to flutter without displacing them. An all-encompassing evaluation of various factors is imperative before arriving at a premature diagnosis."}},{"id":"-SQaZlWWRQ","type":"paragraph","data":{"text":"Contributing Influences "}},{"id":"KdRgrNR71C","type":"paragraph","data":{"text":"Beyond wind speed and direction, the orientation of shingles contributes to the degree of roof damage. Shingles located on the side facing the wind, as well as those along the hips, ridges, and eaves, are more susceptible to adverse effects."}},{"id":"ZqT2zNA0_k","type":"paragraph","data":{"text":"The method of installation and attachment equally influences shingle vulnerability. The absence of nails, improperly driven nails, or shingles installed using unsound techniques heighten the likelihood of wind-related harm. Certain shingle types exhibit greater resistance to wind. Dimensional shingles, featuring added rigidity due to their laminated extra layer, are less prone to wind-induced damage. Notably, dimensional shingles tend to detach in sections rather than incurring creases on individual shingles."}},{"id":"1ig6x71QXh","type":"paragraph","data":{"text":"Alternate Sources of Damage"}},{"id":"ktLaKezx_3","type":"paragraph","data":{"text":"As mentioned, there are scenarios where other causes of loss mimic the traits of wind damage, encompassing creases, cracks, removal, and other manifestations. For instance, compromised sealant strips may arise due to various factors, including aging, and may not necessarily denote wind-related impairment. Here are several frequently observed causes of loss that may erroneously be attributed to wind damage."}},{"id":"RkQib2MpFl","type":"paragraph","data":{"text":"Damage Resulting from Human Activity "}},{"id":"BivsBQxCqR","type":"paragraph","data":{"text":"Attempts to replicate wind damage on shingles often leave discernible evidence. As wind-induced damage rarely generates vertical or partial tears, irregular tears lacking creases are more likely indicative of human-induced harm. Endeavors to pry up shingles typically lead to tears or creases that do not extend across the entire shingle."}},{"id":"JIjPQNwVrJ","type":"paragraph","data":{"text":"Vertical Racking"}},{"id":"MnC9xasivO","type":"paragraph","data":{"text":" Vertical racking, a rapid and efficient installation technique embraced by many roofing contractors, comes with reservations from entities like the National Roofing Contractors Association and the Asphalt Roofing Manufacturers Association. This method involves the sequential installation of shingle columns from the eave to the roof ridge. During the installation of the adjacent column, the roofer must lift the outer tabs of the initial column to integrate the shingles of the second column, which can compromise the seal strip. Hasty or improper lifting can result in curls, tears, and blemishes that might be mistaken for wind damage. In certain cases, the shingles are interwoven without lifting the adjacent shingle, and a fastener may be omitted, reducing the number of nails securing the shingles by 25% and increasing their susceptibility to wind uplift."}},{"id":"7x67SpkESZ","type":"paragraph","data":{"text":"Defects in Manufacturing "}},{"id":"DDm0hRQw5n","type":"paragraph","data":{"text":"Manufacturing flaws may not be immediately evident upon installation, yet indicators could surface over time, mimicking the manifestations of wind damage. A key distinction lies in the location of creases or cracks, both within individual shingles and across the entire roof. Manufacturing defects typically exhibit consistent patterns throughout the roof, as opposed to being more pronounced on windward sides and edges. Creases or cracks may also manifest in fully sealed shingles, often nearer to the middle, while wind-damaged shingles tend to show creases near the top."}},{"id":"tTkLQxTYeG","type":"paragraph","data":{"text":"Accurate Identification of the Root Cause Distinguishing between wind damage and other forms of impairment entails subtle yet meaningful distinctions. Conducting a meticulous inspection is imperative for an accurate diagnosis. In addition to assessing the roof's condition, a qualified expert incorporates weather data from reliable sources, such as the National Oceanic and Atmospheric Administration, alongside other contextual cues in their evaluation. Wind of sufficient intensity to inflict roof damage invariably affects other elements such as shutters, tree branches, neighboring roofs, and collateral structures."}},{"id":"ALZ1RaJsqJ","type":"paragraph","data":{"text":"Shingle damage can leave a residence exposed to water infiltration, making the precise identification of the cause and scope of loss imperative for determining subsequent steps.
